I had this 12bolt I was going to use in my 72 GS455 clone drag car. I asked around over at the Chevelle board and some guy over there needed my "CCF" 12 bolt a whole lot more than me. So now I'm looking at just buying a Currie 9" or a Strange S-60 any opinions. This car is going to be a bracket racer only no street driving. Spool or Posi. Long term goal is to get this car in the 10's within 5 years.
